You, of course, are free to hold such an opinion and express it. Law enforcement is not free to do so.
Law enforcement must operate within the constraints of the Constitution. They may not arrest because they do not like your looks. They must comply with the 4th Amendment and arrest an individual only upon probable cause that an individual has committed a crime.
The "law" under which the 177 were arrested and detained under unconstitutional $1,000,000 bonds makes it a criminal act to sport certain insignia and calls a peaceable assembly an overt act in furtherance of a conspiracy. All this and more of what is happening in Waco ought to concern anyone who claims to be awake to the stripping away of American's liberty.
I have a feeling if these were Bloods and Crips no one would be complaining except Al Sharpton. :P - tongue in cheek.
don-o said it VERY WELL. He really cuts to the chase — the right to assembly and free association is fundamental in America; police at Waco not only deprived these people of their right to assembly, they destroyed the financial and personal lives of all those arrested.
